High Quality Tadanafil Raw Materials

Production philosophy

Our company focuses on the research and production of Tadanafil raw materials, adhering to the concept of quality first and honest management. We implement full process control from raw material screening, synthesis production to finished product delivery, strictly controlling product purity and various impurity indicators. The laboratory is equipped with professional testing equipment and uses HPLC and other methods to conduct full project testing, ensuring that each batch of products must be tested and providing COA testing certificates along with the batch. The company adheres to industry standards, values quality stability, and achieves good batch consistency. Adhering to the business principle of honesty and pragmatism, valuing customer needs, standardizing warehousing and logistics, and fully retaining production and testing records, we are committed to providing customers with reliable product quality and thoughtful service, and are committed to providing customers with stable and reliable raw materials.

The quality of Tadanafil raw materials is strict and controllable. The main purity of the product is stable at over 99%, with high purity and stable activity. The content of various impurities is extremely low, effectively avoiding quality problems such as excessive impurities and impure ingredients. The product has a regular white crystalline powder appearance, stable physical and chemical properties, and various indicators such as solubility, melting point, drying loss, ignition residue, and heavy metals meet industry and pharmacopoeia standards. Relying on precision detection equipment such as HPLC, GC, LC-MS, etc., complete the full project testing of purity, related substances, degraded impurities, residual solvents, etc., and accurately control every quality indicator. All products are subject to batch management, and each batch of products undergoes double check and sample traceability. Authoritative COA quality inspection reports can be provided. Fully compliant production and operation, strict quality control throughout the entire process of production, warehousing, and delivery, ensuring high consistency of product batches, stable and reliable quality, and honest protection of customer procurement rights and usage safety.

Content (purity) detection method (HPLC high performance liquid chromatography)
High performance liquid chromatography was used to accurately determine the main content of Tadanafil. A dedicated C18 chromatographic column was selected, and acetonitrile water system was used as the mobile phase. A constant flow rate, column temperature, and detection wavelength of 285nm were set, and the main peak content of the sample was accurately calculated through standard reference calibration. This method has high separation efficiency and can completely separate the main peak from various impurities, effectively avoiding interference. The purity of our factory's finished products is stable at over 99.0%, with accurate data and good repeatability.
2, Regarding substance and impurity detection
Comprehensive screening of single unknown impurities, known degradation impurities, and intermediate impurities in Tadanafil was conducted using liquid chromatography, with strict control of the total impurity limit for single impurities. By scanning peak purity and comparing spectra, trace impurities are accurately identified, and residual intermediates and degradation products in the production process are strictly controlled to ensure extremely low impurities, clean purity, and stable batches of the product.
3, Residual solvent detection (GC gas chromatography method)
We use headspace gas chromatography to detect residual organic solvents such as ethanol, methanol, and ethyl acetate used in the production process. We strictly follow the pharmacopoeia limit standards to determine and prevent excessive solvent residue, ensuring the safety of raw materials and no residual pollution.
4, Comprehensive testing of physical and chemical indicators
Strictly implement full quality inspection: appearance identification, dry weight loss (moisture) testing, ignition residue testing, heavy metal testing, solubility testing, melting point testing, etc. Comprehensively control the stability of raw materials, eliminate quality issues such as moisture, excessive ash content, and heavy metal content.
5, Mass spectrometry confirmation detection (LC-MS qualitative)
Perform liquid chromatography-mass spectrometry qualitative confirmation on each batch of products, confirm the authenticity and accuracy of Tadanafil ingredients through molecular weight matching, eliminate problems such as adulteration, mixing, and ingredient mismatch, and fundamentally ensure the authenticity and authenticity of raw materials.
